....trained pathologists using the system. The user examined several slides, thoroughly searching each slide for any abnormality, as they would with a real microscope. We performed tracing for several sessions, and derived an abstract model of user behavior. We present highlights of the detailed model [4] here.

Similarly, magnification also worked well as a predictor for inter request time, also known as think time. 4 SIMULATION We simulated the system to quantify the potential benefits of using a proxy.

....the inter request times. Instead, we randomly choose values from a histogram of the values in the traces. 4 Simulation We simulated the system to validate our hypotheses and to quantify the potential benefits of using a proxy. Here we present highlights of a more complete simulation study [5]. We are interested in determining the number of clients that can be supported at varying quality of service levels. To this end, we instrumented the Virtual Microscope client and server as well as prototype of the proxy. From the resulting execution traces on a server with a single backend ....
